The question involves diagnosing the condition associated with an 11-year-old boy experiencing symptoms such as a persistent cough for 15 days and cervical lymphadenopathy, based on lymph node examination findings. Given the options, we analyze each:
Leprosy: Characterized by skin lesions and peripheral nerve involvement. Cervical lymphadenopathy is atypical.
Sarcoidosis: Often presents with bilateral hilar lymphadenopathy and systemic symptoms. It can involve multiple systems but is less common in children and would typically involve more pulmonary symptoms.
Syphilis: Generally presents with other symptoms like painless ulcers or rashes. Lymphadenopathy is possible but cervical involvement alone in this context is less likely.
TB: Tuberculosis is a primary suspect in pediatric cases with a cough and cervical lymphadenopathy. TB lymphadenitis is the most common extrapulmonary manifestation in children and presents as cervical lymph node enlargement.
Based on the clinical presentation, the persistent cough and cervical lymphadenopathy are most indicative of TB (Tuberculosis) in this scenario.
